Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

500 watts x 1 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

900 watts x 1 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

Not Bridgeable
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison.

1800 watts

Power Specifications - Subwoofer Channel

RMS Power @ 4 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
RMS Power @ 2 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
RMS Power @ 1 ohm
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 1 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
Peak Power Output

Often times this maximum is achieved during a brief musical burst, such as a drum accent or low bass hit. Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison. This is the peak power output for the amplifier's 5th channel.

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

900 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.5%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 200 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
Off / 15 / 25 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
96 dB
Bass Boost
The objective of the bass boost is to get more kick out of your subwoofer. It is a circuit that emphasizes the lower frequencies at a given point. The bass boost should always be set first before setting the gain. This feature is known for destroying subwoofers and is commonly used incorrectly, so be cautious.
0 - 18 dB
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
30A x 2 
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.

The Best Power Amp Ever made by Kenwood

April 6, 2011

I've read reviews about owners from Wisconsin, Norway and other cooler parts of the world. To tell you I have used this Amp in my Pajero in a place like Kuwait where the scorcing heat temperatures are 50 Degrees minimum in summer. This has been ever since I purchased it in 2005 until date this Amp ROCKS the heat. Which means a default 50 Degrees heat multiplied with another 30 degrees of temperature which the Amp generates when used. So the Amp comfortably plays in 80 degrees heat for a number of hours. The first time I opened up the volume, it literally sent a complimentary CRACK on the Rear Glass of my Jeep. This Amp is supported with a equally qualifiable subwoofer cone magnet. The Amp has beautiful fuse control if the car creates unusual hiccups. This happened once with me, but God is Great nothing happened to the Amp it was only the Fuse which was to be replaced which cost hardly a Dollar. This is one of the best buys any Car Stereo Freak can invest in and be happy for the rest of his journey. Lately I have changed the Front-end Stereo Deck from a RockFord CD Deck to an all Inclusive Pioneer USB System and amazed to hear that this Amp performs even more better. Infact I had to reduce the BASS settings to avoid Wind Shield Cracks....wink. Go for it. These things are made once in a lifetime.

Great amp!

August 19, 2009

For over a year now this amp has amazed me, puts out a true 900 rms, in fact when we tested it showed 960. To anthony from Oakland, CA, Alot of times you wont even hear a difference between 500-1000rms power, alot is involved such as the voltage the amp revives, the decks pre-outs, the different subs efficiency and x-max, and the enclosure they are in.

what a monster amp!!!

November 11, 2008

ok so i bought this amp in fall of '06 and it still surprises me, considering i have blown up dozens of speakers with it. you know how some people get. "oh yeah it aint no 2000 watts... let me hook up my subs they can take it." i love the look on their faces when the smoke comes rolling out the trunk. after 2 years of ownership i still love this amp. i am using it to power 2 dub (audiobahn) 10's rated for 2400 watts for the pair, and they love this amp. i was running 2 1100 watt xplods in a nice bandpass box for the first year, and they did great too. anyway to anyone who is having a problem with this amp "cutting out"... take off the bottom cover and look for some scorch marks on it... if there is any, just find the transistor leads that are touching the cover and bend them down towards the cicuit board a bit.... seems that the factory didnt trim the leads down enough. i had that problem with mine for the first few months of owning it but it wasnt a hard prots pushing close to 2200 watts on certain songs atblem to fix at all. i have had mine rated, and i 1 ohm, and still stable to the last note. this amp is WELL worth the price, get it and you wont be disappointed at all. the problem with the circuit leads was stupid but easily fixable so im not gonna mark the review down any for it.

Amp stopped working!

May 4, 2006

After about 4 months of use the amp stopped working. But when it was working it hit hard but it didn't feel like 900 rms. My friend had a 840 rms Audiobahn amp and his setup was hittin harder then mines. I would not buy this amp again. But it has a lot of rms for the price.

Holy Smokes!

April 24, 2006

Lots of power! Amp responds very quick to transients and controls the subs beautifully. Stays COLD even after 50 mins of test tones below 40 htz. CEA-2006 Compliant means a TRUE and honest 900 watts RMS at 14.4 volts. I do reccomend mating it with a 1.0 cap so it doesn't run out of current. Amp is the same size as the KAC-7252 and the flat black and stainless finish are a clean and grown-up look. If your looking for bling what this amp lacks in that department more than makes up for in performance!

I have had this amp for awhile now and it made my sub sound much better. Not only does it push a lot of watts it will make your sub clear. I have blown the fuse a couple of times which I guess is better than blowin the amp but mostly might fault for turning it up to much just to test it. I would definately recommend this amp.
